It doesn't matter what steroids you use, when you go off cycle, you will lose size and strength. But you won't lose all of it, and each time you will end up with a better base to work with the next time around. If you put together many years of correct cycling, diet and training, you will develop a mature muscle mass that is semi-permanent in nature. That's the goal. And, that's why this isn't a hobby....it's a lifestyle.
In the 70's, we often did dbol only cycles, because that was the most available drug out there. I kept a lot of that overall size and strength.......but then the genuine little blue dbols made in the USA were way different than the shit dbol (not all, but most brands) available today.
